To all whom it may concern .7 7 Bell; known thatl, JOHN SGHADE, Jr., a citizen of the United States, and'resident of the-borough of Brooklyn, county of Kings,

city and State of New York, have inven'ted .certain new and useful Improvements in Spring Fastening Devices, of which the following is aspecification, accompanied by drawings; v

This invention, clips'or fastening of the electrical conductors,

relates to spring terminal devices for the terminalsv and the objectsofthe invention are to'enable the conductor Further'ob'jects-of the invention will herea ing. -the-:features ,tions of elements, having the general mod tolbefirmly gripped and clamped in defined position, permit the ready insertion and removal of the conductor, and insure good i 5 electrical contact atQall-times betweenthe fi-ig'cond-izctor and the fastening device.

L'This application is in 203 'inafien appear; tion consists, of lying out all of e 'ofpperation substantially as hereinafter fully described and claimed in this specification and :Ishown n the accompanying drawings,in-Wl1ich1-T view in- Figure 1' is a perspective view'ofiafaetening device embodying the invention; ig. 2 isa perspective View of a,modifica;-- tion lpfthesame; Fig. 3'; is a perspective. view 'oflano'ther modification; Fig. 4 is a perspective of several difi'erent 'forms of'elements-which 1" ay'be combined to make the'fastening devilib; Figs. 5 and ,6 are perspective views jof'inpdific'ations; Fig.

In the preferred form of theinvention, the fastening device is adapted to be secured to a base or support A, although the int/en tion may be used in any connection in. which it is found applicable. The main'portion ofythe device, comprising the body member, vB and the spring member G is preferably made from asingle piece of resilient mate; rial as for instance metallic'ribbonQ Referring more particularly to Figs-l metallic ribbon is bent into substantially the body member,

The body member is provided in F1g. 1 with integral ears or tabs F,extending in longitudinal planes at each side of stationary resistant member. .These can F the insertion of a conductorI-I.

In Fig. 6 the'jbody and spring members and U respectively and a single wire staple or loop V is driven into the base or support A and adapted to lie inthe slots T and U.

In Fig. 7 the ears or tabs W are provided on the spring member O instead of on the body member, while the body member is provided with the bent portion X forming the resistant member. 1n this latter form of the device shown in Figs. 7 and 8 the spring member is pressed toward the body member in order to' insert the wire throug the apertures Y in the ears, and beneath the bent portion X of the body member as indicated in Fig. 7

I am not to be understood as limiting the invention to the forms of device shown in the drawings, for the device may obviously be made in many varying forms without departing from the spirit of the invention as defined by the appended claims.

I claim and; desire to obtain by Letters 1. A fastening device for electrical conductors, comprising a piece of resilient metal bent intoU-shaped form, one leg of the U-shaped piece forminga body member, and the other leg forming an opposing spring member normally separated from the body member, one member being bent to form a Vshaped retaining portion, the apex of which extends toward the opposing memher, and resistant members extending in longitudinal planes at each side of the fastening device and lying opposite to each other in a transverse plane,the said resistant members lying outside of the said V-shaped retaining portion and being constructed to receive and hold a conductor thrust transversely through the retaining portion and through said resistant members.

2. A fastening device for electrical conductors, comprising a piece of resilient metal bent into U-shaped form, one leg forming a body member and the other leg forming a spring member opposed to the body member, and a separate U-shaped re: sistant member adapted to embrace the body and spring members and having means for retaining a conductor.

3. A fastening device for electrical conductors, com risln a piece of resilient metal bent into U- iape form, one leg forming a body member and the other leg forming a spring member opposed to the body mem-. her, and a separate U-shaped resistant member, adapted to be secured to the body member, thelegsof said resistant member extending toward the spring member and having means for retaining a conductor.

4:. A fastening device for electrical con- 3 ductors, comprising a piece of resilient metal 1 looped on itself to form a spring and having of the device are provided with the slots T one end bent in a; reverse direction to the loop to formwith the bend of the loop an angular wire-engaging portion, and a re sistant member formed of wire located at the opposite end of the loop and having an aperture for receiving a conductor, whereby when the spring is forced toward the resistant member,a conductor may be inserted in the said Wire-engaging portion and through the aperture-in the resistant memher and be firmly gripped in defined position by the retractive force of the spring.

5. A fastening device for electrical conductors, comprising a body member, a resistant member formed of wire projecting upward from the body member and having an aperture to receive a conductor, and an opposing. spring member rojecting upwardly from the body mem er at the forward end of the body member, then downwardly toward the resistant member and in roximity thereto, then upwardly away roni the body member, thereby forming a wire-engaging portion adapted to cooperate with the apertured resistant member to firmly grip and hold aconductor in detinec position by the retractive force of the spring. 6. A fastening device for electrical conductors,comprising a piece of resilient metal bent into U-shaped form, one leg of the U- shaped piece forming a body member, and the other leg forming an opposing spring member normally separated figom the body meniber, one member being bent to form an angular retaining ortion extending toward the opposing mem er, and a resistant member extending in a longitudinal plane at one side of the fastening device, the said resistant member lying outside of the said angular retaining portion and being constructed to receive and hold a conductor thrust transversely through the retaining portion and through said resistant member.

In testimony whereof I have signed this specification in'the presence of two subscribing witnesses.
